Challenge fees are the single biggest recurring cost for most prop traders. If you're running through multiple firms, you could be paying hundreds — sometimes thousands — of dollars a month in challenge fees before a single payout lands. The obvious question is: can you write any of that off?
The short answer is yes, in most cases — but it depends on how your trading income is classified and where you're based. Here's what actually matters.
What Is a Challenge Fee?
A challenge fee is the upfront cost you pay to attempt a prop firm evaluation. You're paying for the right to trade a simulated account and prove you can follow the firm's rules. If you pass, you get funded. If you fail, you pay again.
From a financial standpoint, it's a business expense — the cost of acquiring access to capital. That framing matters a lot when it comes to taxes.
Are Challenge Fees Deductible in the US?
For US-based traders, whether challenge fees are deductible comes down to one question: are you classified as a trader in securities for tax purposes, or are you an investor?
The IRS distinguishes between the two based on the frequency, regularity, and volume of your trading activity. Most funded prop traders — especially those trading full-time across multiple firms — qualify as traders rather than investors.
If you're classified as a trader, you can deduct business expenses directly on Schedule C. This includes:
- Challenge fees paid to prop firms
- Subscription fees for trading platforms and data
- Education and training costs
- Home office expenses
- A portion of your internet bill
If you're classified as an investor, your ability to deduct trading-related expenses is significantly more limited under US tax law.
The key test: Are you trading with continuity and regularity, with the primary purpose of making a living from trading? If yes, you likely qualify as a trader.
Important: This is general information, not tax advice. Consult a qualified tax professional who understands trader taxation — it's a specific area of tax law and most general accountants don't know it well.
Are Challenge Fees Deductible in the UK?
UK-based traders have slightly cleaner rules. If prop trading is your trade or business — meaning you're doing it commercially, regularly, and with the intention of making a profit — challenge fees qualify as allowable business expenses under HMRC rules.
HMRC doesn't have a specific "trader classification" test like the IRS. Instead, they look at whether the activity constitutes a trade. For most full-time or serious part-time prop traders, the answer is yes.
If your prop trading profits are taxed as self-employment income (rather than capital gains), your challenge fees are deductible against that income.
The Rest of the World
Most jurisdictions follow the same principle: if you're running prop trading as a business and reporting it as business income, your challenge fees are a legitimate cost of doing business.
Germany, Australia, Canada, and most EU countries allow self-employed traders to deduct business expenses including costs incurred to generate income — which is exactly what a challenge fee is.
The complication usually comes when traders report their prop trading income as a side income without formally treating it as a business. In that case, deducting expenses becomes harder to justify.
What Records Do You Actually Need?
Whether you deduct challenge fees or not, you need clean records. Tax authorities want to see:
- Date of each payment
- Amount paid (in your local currency at the time of payment)
- Which firm the fee was paid to
- Method of payment (card, crypto, bank transfer)
- Outcome (passed, failed, refunded)
If you paid in USD but report in EUR, GBP, or AED, you also need to record the exchange rate at the time of payment. This is where most traders fall short — they have the fees somewhere in their email or bank statement, but not in a consolidated, organised format their accountant can actually use.
The Real Problem: Most Traders Can't Prove Their Costs
Being entitled to a deduction is one thing. Being able to prove it is another.
If you've been trading across FTMO, Funding Pips, TopStep, and two other firms over the past year — with fees paid by card, PayPal, and USDT — reconstructing all of that at tax time is painful. Most traders either miss deductions they're entitled to or hand their accountant a mess of screenshots and bank statements.
The fix is straightforward: record every challenge fee as you pay it, assign it to the correct firm, and keep a running total. That's what a clean bookkeeping ledger does — and it's exactly what PropFirmTerminal handles automatically.
Checklist: Challenge Fee Deductibility
- Am I trading with regularity and continuity? (not just occasionally)
- Am I reporting prop trading income as business/self-employment income?
- Have I spoken to a tax professional who understands trader taxation?
- Do I have a record of every challenge fee paid this year — date, amount, firm, currency?
- Have I converted all foreign currency fees to my reporting currency at the correct rate?
- Are my fees separated from personal expenses in my records?
Frequently Asked Questions
Can I deduct a challenge fee I paid but didn't pass? In most cases, yes. The deductibility of a business expense doesn't depend on whether it was successful — it depends on whether it was a genuine cost of doing business. A failed challenge is still a real business expense.
What about challenge fee refunds? Do I still deduct the fee? If you received a refund, you only deduct the net cost. If you paid $500 and got $500 back, there's nothing to deduct. If you got a partial refund, deduct only what you actually kept paying.
I pay challenge fees in USDT. How do I record that? You need to record the USD (or local currency) value of the USDT at the time you sent it, not just the token amount. Most accountants will ask for this. PropFirmTerminal automatically records the fiat value when you import crypto transactions.
Do I deduct challenge fees in the year I pay them, or the year I pass? Generally, in the year you pay them — expenses are deducted when incurred, not when the outcome is known.
My accountant has never heard of a prop firm. What do I tell them? Frame it as self-employment income from a financial services business. Challenge fees are your cost of accessing capital. Payouts are your revenue. Your accountant handles businesses with costs and revenue every day — this is the same thing in a different wrapper.
PropFirmTerminal records every challenge fee automatically — date, amount, firm, currency, exchange rate. When your accountant asks for your year-end records, you export a report instead of digging through emails. Start your free 5-day trial →
